Local resource delivery network

ABSTRACT

A local area network (LAN) may contain several local computing devices that are in communication with a remote network storage provider that is not part of the LAN. Resources may be available from the remote network storage provider. When a user requests a resource using a first local computing device in the LAN, the first local computing device may check the other local computing devices on that are in the LAN for the resource before requesting the resource from the remote network storage provider. If the resource is available within the LAN, the resource is not requested from the remote network storage provider.

BACKGROUND

Generally described, computing devices and communication networks can be utilized to exchange information. In a common application, a computing device can request content from another computing device via the communication network. For example, a user at a personal computing device can utilize a software browser application to request a Web page from a server computing device via the Internet.

A user may have own several digital resources (such as, photos, videos, document files, audio files, for example) that they store on one or more computing devices under the user's control. The storage available on the user's computing device is limited and as a result, they user may not be able to store a large volume of resources, or store resources that are large in size. In addition, the user may wish to access the same resource across multiple computing devices. For example, the user may desire to access a file from his work computer, his home computer, or his mobile computing device. As a result, a user may decide to store some resources remotely using a network storage provider. The user may be able to upload or store the resource to the remote network storage provider using a first computing device and access the resource using a second computing device. In addition, a user may store infrequently accessed resources on the remote network storage device to make room for frequently accessed resources on his computing devices.

DETAILED DESCRIPTION

Overview

Use of a remote network storage provider enables a user to store infrequently used resources or large resources, or to share resources among several computing devices. Current use of a remote network storage provider typically requires a computing device to request a resource from the remote network storage provider which is not associated with its local area network (LAN). In some cases, a user may be sharing a resource among several computing devices that are nodes of the same LAN. For example, a resource may be shared between a desktop computer and a tablet within the same LAN. In such cases, the retrieval of the resource from the remote network storage provider may be unnecessary and inefficient. For example, if the resource is available from another node computer within the LAN, it can be retrieved easier and more efficiently locally.

Accordingly, the present disclosure is directed to the management of resources within a LAN. In one embodiment, a user computing device is associated with a LAN and may be in communication with a remote network storage provider. A user operating the user computing device may request a resource. The user computing device may, in some embodiments, detect other computing devices connected to the LAN. The user computing device may also determine if any of the detected computing devices have the resource requested by the user. If none of the detected computing devices have the resource, or if the detected computing devices have an outdated version of the resource, the user computing device may request the resource from the remote network storage provider. Alternatively, if one of the detected computing devices has the resource, the user computing device may obtain the resource from the detected computing device storing the resource. In some embodiments, the user may upload to and request resources from the remote storage computing device using a resource manager client.

For example and illustrative purposes only, suppose a user uses a remote network storage provider to store photos. The user may utilize a resource manager client executing on his laptop to upload “photo1.jpg” to the remote network storage provider. The laptop may be connected and part of the user's home wireless network (e.g., the user's LAN), but the remote network storage provider may not be connected to the LAN and is accessible only through a wide-area network such as the Internet. Once uploaded, a first copy of “photo1.jpg” is stored at the laptop, and a second copy of “photo1.jpg” is stored at the network storage provider. In addition to the laptop, the user may also have a mobile phone connected, and part of, the LAN. The user may want to view “photo1.jpg” on the mobile phone. Typically, the mobile phone would request “photo1.jpg” from the remote network storage provider through a website or mobile application. In the embodiments disclosed herein, however, the mobile phone may first check to see if “photo1.jpg” is available from a computing device within its LAN. If the photo is available, the mobile phone may request it from the computing device within its LAN. For example, when the user requests “photo1.jpg” from the mobile phone, the mobile phone may determine that it is available from the laptop. The laptop may then provide “photo1.jpg” to the mobile phone.

More generally, in one embodiment, a first computer system on a LAN determines one or more computer systems that are also connected to the LAN. The first computer system may receive a request from a user for a resource and may also access metadata associated with the resource to determine if a second computer system locally associated with the LAN has a version of the resource. If the resource is available from the second computer system on the LAN, the first computer system retrieves the resource from the second computer system. If the resource is not available from a computer system on the LAN, the first computer system may retrieve the resource from a remote network storage provider. In some embodiments, the accessed metadata may be stored on the first computer system or in other embodiments, the accessed metadata may be stored on another computer within the local area network or on the remote network storage provider. Embodiments may also include the first computer system monitoring metadata stored on the remote network storage provider for updates to the resource and pre-fetching the resource based in part on the metadata. Other embodiments may also include a remote network storage provider or a second computer system on the LAN storing a resource having a first attribute or characteristic and providing the resource to the first computer system with a second attribute or characteristic. For example, the remote network storage provider (or second computer system on the LAN) may store a resource with the file name “FileFromNetworkStorageProivder156664.txt” (first attribute or characteristic) and it may provide the resource with a second file name, “File1.txt” (second attribute or characteristic) to the first computer system. By way of further example, the remote network storage provider (or second computer system on the LAN) may store a resource in a first format (first attribute or characteristic) and provide the resource in a second format (second attribute or characteristic) to the first computer system.

Embodiments of the disclosure will now be described with reference to the accompanying figures, wherein like numerals refer to like elements throughout. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner, simply because it is being utilized in conjunction with a detailed description of certain specific embodiments of the disclosure. Furthermore, embodiments of the disclosure may include several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the embodiments of the disclosure herein described. Further, although various aspects of the disclosure will be described with regard to illustrative examples and embodiments, it can be appreciated that the disclosed embodiments and examples should not be construed as limiting. For example, although the present application will be discussed with respect to certain computing devices, it can be appreciated that the systems, methods, and process described for managing resources may be applied to any computing device that may share resources within a network.

Example Resource Delivery Environment

FIG. 1 illustrates one embodiment of a resource delivery environment 100 containing a network storage provider (NSP) 105 in communication with two local area networks (LANs) 115, 125. In the illustrative embodiment of FIG. 1, the NSP communicates with the LANs via network 180. The NSP may store resources of user computing devices 110, 111, 112, 120, 121, 122 that communicate with the NSP through router/access point 113, 123 and network 180. In one embodiment, a user may upload a resource comprising digitized data (such as a document, video, audio file, image, or the like) to the NSP 105 thereby storing the resource at the NSP. After uploading the resource, the user may access the uploaded resource with any one of its user computing devices 110, 120. Thus, the NSP may act as a means to share resources among the user's computing devices and networks. In addition, the NSP may serve the function of providing additional storage to the user. For example, the NSP may provide storage for the user to archive multiple versions of a document, serve as storage for infrequently used files, or provide storage for backups.

The resource delivery environment 100 in FIG. 1 may be computerized, wherein each of the illustrated components comprises a computing device that is configured, amongst other things, to communicate with other computer devices via network 180. For example, each of the user computing devices 110, 111, 112, 120, 121, 122 may comprise a computing device, such as a desktop, notebook, mobile device, cell phone, tablet, handheld computing device, or other general purpose computing device that may be configured to transmit and receive data to/from other computing devices and LANs via network 180. Depending on the embodiment, network 180 may comprise one or more of any type of network, such as one or more wide area networks, personal area networks, telephone network, and/or the Internet, which may be accessed via any available wired and/or wireless communication protocols. Any other combination of networks, including secured and unsecured network communication links, are contemplated for use in the systems described herein.

In some embodiments, a user may connect his/her user computing devices 110, 120 to a local area network, or LAN. Generally, a LAN is a computer network that interconnects computers in a limited area such as a home, school, office, computer laboratory or shopping area. As is known in the art, one of the defining characteristics of a LAN is relatively high data transfer rates between computing devices that are part of the LAN due to the close proximity of the computing devices. In some embodiments, the LAN may be a wireless LAN, thereby permitting computing devices to connect to the LAN without the use of a cable or wire. In other embodiments, the LAN may be implemented in a wired fashion where computing devices may be connected through the use of a cable or wire.

In some embodiments, the LAN 115, 125 may include a router/access point 113, 123. The router/access point may facilitate communications between the nodes of the LAN such as user computing devices 110, 111, 112. The router/access point may also facilitate communicates between the nodes of the LAN and other computers connected through a wide area network (WAN). For example, in the illustrative embodiment of FIG. 1, router/access point 111 may facilitate communication between user computing device I-A 110A and network storage provider 105. The router/access point 113 may facilitate communication by forwarding data packets using a standard networking protocol such as TCP/IP, for example. In some embodiments, the router/access point 113 may also comprise a modem for connecting nodes of the LAN with computing devices that are not part of the LAN.

As shown in FIG. 1, in some embodiments, the resource delivery environment 100 may include more than one LAN. Each LAN may be geographically or logically separate. For example, LAN A 115 may be the user's home computer network while LAN B 125 may be the user's computer network at her office. Alternatively, the LANs may be geographically co-located but logically separated. For example, LAN A 115 and LAN B 125 may be located within the same office building, but may be separated for security reasons, bandwidth considerations, or other organizational criteria.

With continued reference to FIG. 1, the resource delivery environment 100 can also include a network storage provider 105 in communication with the one or more LANs 115, 125. The network storage provider 105 illustrated in FIG. 1 also corresponds to a logical association of one or more computing devices associated with a network storage provider. Specifically, the network storage provider 110 can include a number of network storage provider Point of Presence (“NSP POP”) locations 106, 108 that correspond to nodes on the communication network 180. Each NSP POP 106, 108 includes a storage component 107, 109 made up of a number of storage devices for storing resources which will be managed and processed by the network storage provider 110 and transmitted to various LANs, such as LAN 115, 125. The storage components 107, 108 may further include additional software and/or hardware components that facilitate communications including, but not limited to, load balancing or load sharing software/hardware components. In addition, the storage components 107, 108 may include a scalable, resizable compute capacity.

In some embodiments, the storage components 107, 108 may store resources uploaded by user computing devices 110, 120 to the NSP. The NSP 105 may allocate a portion storage space for a user to store resources (“user's NSP allocation”). The NSP 105 may restrict access to the user's NSP allocation to other users, thereby making the user's NSP allocation secure. For example, the NSP may allocate 20 GB of storage space to a designated user for the storage of resources. Additionally, the NSP may restrict access to the designated user's allocation of storage space to other users of the NSP. The NSP may, in some embodiments, require verification of user credentials, such as a user name and password. A user may upload a resource from a user computer device 110 to the user's NSP allocation of storage 107, 109 or the user may request a resource stored on the user's NSP allocation. The storage components 107, 108 may also store metadata describing the resources, thereby facilitating efficient management of resources. The content and format of the metadata is described in more detail below with respect to FIG. 2.

In an illustrative embodiment, the storage components 107, 108 are considered to be logically grouped, regardless of whether the components, or portions of the components, are physically separate. Additionally, although the NSP POPs 106, 108 are illustrated in FIG. 1 as logically associated with the network storage provider 110, the NSP POPs may be geographically distributed throughout the communication network 180 in a manner to best serve various demographics of user computing devices and LANs. Additionally, the network storage provider 105 can be associated with various additional computing resources, such additional computing devices for administration of content and resources, DNS name servers, and the like.

Example Components of User Computing Devices

FIG. 2 illustrates one embodiment of a user computing device 110 including a resource manager client 210, a resource manager server 220, a pre-fetch module 230 and resource manager data 240, which may be modules or components of software code that when executed perform the processes described in FIGS. 3-6. Although the functionality of each module will be discussed with reference to particular functions, each module may perform additional functions, and in some embodiments some modules may perform the functionality of other modules herein described. For example, in some embodiments, functionality described herein as being preformed by the resource manager client 210 may be performed by the resource manager server 220. In addition to the resource manager client 210, resource manager server 220, pre-fetch module 230 and resource manager data 240, the user computer device 110 may also have a CPU 201, a memory 202, input-output (I/O) devices 203, and a data store 204. However, generally, the configuration of each user computing device may vary. For example, each computing device may have different CPU capacities or configurations. Additionally, one or more of the above illustrated components, such as a data store, may be omitted.

In some embodiments, the resource manager client 210 is a module or component that facilitates the management of resources for a user. The resource manager client 210 may be an executable application, or “front-end”, that provides a mechanism for the user to interact with the user computing device 110 to upload resources to the NSP and request resources from the NSP or other user computer devices. The resource manager client 210 may be, in some embodiments, an application capable of being displayed in a web browser such as a dynamic web page or web application. In other embodiments, it may be a separate executable with a graphic user interface (GUI) for choosing which resources to upload to the NSP or which resources to request from the NSP or the other user computing devices within the user computing device's LAN. In some embodiments, the resource manager client 210 may integrate with the existing file browser of the user computing device nd provide the user with the ability to manage resources through the use of context sensitive menus. In other embodiments, the resource manager client 210 may be a command line tool allowing the user to manage resources through the use of commands or scripts. Some embodiments may combine elements of a command line tool, integrated tool or stand alone tool.

The resource manager client 210 may provide, among other things, the basic functionality to manage resources which may include uploading resources, retrieving resources, providing status of resources, providing version information and location information of resources, and providing an list of resources available in the user's NSP allocation. For example, the resource manager client 210 may provide the basic functionality through a list interface, tree interface or command line prompt. For example, a user may be able to upload a resource using a file chooser user interface component that is displayed by the resource manager client 210. In a command line embodiment, a user may be able to access the basic functionality through the use of command line prompts. In some embodiments, the resource manager client 210 may interact or interface with another application. For example, the resource manger client 210 may be a plug-in to a web or file browser, or may integrate with applications that create or edit resources such as word processing applications, photo editing applications, or video editing applications, for example.

The resource manager client 210 may also facilitate the retrieval of resources. For example, after displaying the list of available resources to the user, the user may be able to select a particular resource for retrieval by clicking on the resource or otherwise selecting it. In other embodiments, resource retrieval may be facilitated by the resource manager client 210 through the use of a command whereby the user provides the name or unique identifier of the resource for retrieval. For example, this may be done through the use of a command line tool or text box. In some embodiments, the resource manager client 210 may allow the user to allocate space in the local data store 204 (“user's local allocation”) to mirror the resources, or a subset of the resources, available from the NSP 105. In such embodiments, the resource manger client 210 may allow the user to perform a “Get All” operation which will retrieve all of the available resources from the user's NSP allocation or all the resources of a particular group or subset available from the NSP 105 within the user's NSP allocation.

In some embodiments, the resource manager client 210 may communicate with the resource manger server 220 to determine the current status of resources, or to perform resource put (upload) or get (retrieval) operations. The resource manager server 220 may be a background process, or daemon, executing in the background of the user computing device. In other embodiments, the resource manager server 220 may execute as a daemon on a dedicated server located on the LAN of the user computing device 110. The resource manger server 220 may expose a network socket allowing the resource manager client 210, or other resource manager server instances within the LAN to connect to it in order to request a resource, get status on a resource, or upload a resource to the NSP. The resource manager server 220 may also establish connections to the NSP or other resource manager server instances within the LAN to request resources, receive resources, request and receive status, and receive and request resource availability data.

The resource manager server 220 may manage resources with the assistance of metadata describing the resources, which will be generally referred to as “metadata”. Illustratively, metadata may include data that describes a resource and facilitates the management of resources without the need to manipulate the resource itself. Since the metadata is likely smaller than the resource, it can be transferred more efficiently throughout the resource delivery environment thereby minimizing network bandwidth. The metadata may include, among other things: a unique resource identifier that uniquely identifies the resource, status information pertaining to the resource (such as whether the resource is locally available or whether a locally available resource is synched with the version of the resource stored at the NSP), version information, whether the resource has been edited locally and/or the computing devices from which the resource may be available. In some embodiments, the resource manager server 220 may store the metadata in the resource manager data store 240.

In some embodiments, the metadata may also include authentication information related to the resource. For example, the metadata may include an encrypted token that restricts access to the resource to only those resource manager server instances capable of decrypting the token. In other embodiments, the metadata may include authentication information that describes the identity of the resource manager server instances that may access the resource. For example, upon installation, each resource manager instance may generate a unique key that is encrypted and registered with the NSP 105. A user may be able to grant permission to a resource manager instance to access a resource. At that time, the metadata of the resource may be updated to include the encrypted unique key of the resource manager server instance. In other embodiments, the metadata may be encrypted so that only those authorized resource manager service instances may access the metadata. Encryption of tokens, unique identifiers, and metadata may be done using any known encryption algorithm.

In some embodiments, the resource manager client 210 may display some or all of the metadata in a GUI so that the user may know the status of resources. In other embodiments, the metadata may be hidden from the user so that from the user's perspective all resources from the user's NSP allocation appear to be locally available. In such embodiments, when the user selects a resource for viewing or modifying, the resource manager server 220 may use the metadata to determine if the resource needs to be retrieved, and if so, from which computing device to retrieve the resource.

The resource manger server 220 may perform some resource management functions periodically. For example, the resource manager server 220 may periodically request metadata updates from the NSP. The resource manager server 220 may request from the NSP an updated metadata set for the resources in the user's NSP allocation. The NSP, in response, may provide an updated metadata set to the resource manager server 220, which may then notify the resource manager client 210 with updates if needed.

In some embodiments, the resource manager server 220 may periodically broadcast on the LAN a notification data packet that may notify other resource manager servers on the LAN that it is participating in the resource delivery environment 100. The resource manager server 220 may also check for other resource manager server instances that are executing in the user computing device's LAN by executing a packet analyzer or network sniffer configured to detect the broadcast of notification data packets originating from other resource manager server instances. In one embodiment, the notification data packet may provide enough data to notify the resource manager server 220 of the other instances of the resource manager server. In other embodiments, the notification data packet may include additional data, such as metadata related to the resources that could be served from the resource manager server.

In some embodiments, the resource manager server 220 may also maintain a list or data structure tracking the available computing devices on its LAN as well as those participating in the resource delivery environment 100 (that is, those computing devices running a resource manager server instance). The list or data structure may contain, for example, the IP address of the participating computing device, a device identifier used by the resource delivery environment 100 to identify the computing device, or resources available from the participating computing device. In some embodiments, the resource manager server 210 may access or consult the list or data structure before it requests a resource from the NSP 105. For example, the resource manager server 220 may use the list or data structure to determine which computing devices to poll for a resource request (see FIGS. 4A-4B) or it may use the list to determine which computing device has the most recent version of a resource. In some embodiments, the list or data structure is stored in the resource manager data store 240.

In some embodiments, user computing devices may not be optimized to, capable of, or configured to process resources having particular attributes or characteristics. In such embodiments, the resource manager server 220 may, for example, change an attribute or characteristic of a resource, or otherwise create a new version of a resource having the preferred attribute or characteristic, before providing it to a requester. This may occur in embodiments where a first user computing device on the LAN stores and processes resources having a first attribute or characteristic, while a second user computing device on the LAN processes resources more efficiently when they have a second differing attribute or characteristic. For example, a first user computing device that is a desktop might store a video resource in an uncompressed video format. A second user computing device, such as mobile phone, may request the resource. Due to the limited storage capacity of the mobile phone, the mobile phone may process the video more efficiently in a compressed format. When the mobile phone requests the video resource from the desktop, it may request the desktop to reformat the video into the compressed format. In others embodiments, the resource manger server 220 may also contain a module that allows for streaming of video or audio resources. That is, as opposed to converting the resource to a different format before delivery, the resource manager server 220 may stream it to the requester. In other embodiments, an attribute of the resource may be changed. For example, the resource manager server 220 may provide a resource in a read-only format, or it may truncate or shorten a file name before providing the resource to the requester.

The resource manager server 220 may also contain or communicate with pre-fetch module 230. The pre-fetch module 230 may analyze metadata describing the resources available (“resource availability data”) on the user's NSP allocation and determine whether any of the data should be requested before the user requests the resource. For example, the pre-fetch module 230 may analyze the resource availability data and obtain the most recently added or updated resource. In other embodiments, a user may be able to configure the pre-fetch module through the use of pre-fetch preferences. A user may, for example, set a preference to pre-fetch resources of a particular file type or with file names containing particular strings of characters. For example, a user may define pre-fetch preferences on his work computing device to pre-fetch any resources available from the user's NSP allocation that is a word processing file or any file with the string “work” in the filename. To facilitate pre-fetching, the resource manager server 220 may periodically request updated metadata from the NSP, extract the resource availability data from the metadata, and then feed the pre-fetch module the resource availability data. The pre-fetch module may then analyze the resource availability data in light of the pre-fetch preferences and pre-fetch resources accordingly.

In some embodiments, the resource manager server 220 accesses the data store 204 of the user computing device to store resources retrieved from the NSP or from other user computing devices executing a resource manager server instance on the LAN. In some embodiments, the resource manager server 220 may be configured to utilize a portion of the data store 204 for resources (“user's local allocation”). The user's local allocation may be smaller than the user's NSP allocation. For example, the user's local allocation may be 5 GB of storage while the user's NSP allocation may be 100 GB of storage. In such embodiments, the resource manager server 220 may manage the resources in the user's local allocation so that the user's local allocation is not exceeded. In some embodiments, the resource manager server 220 may utilize a first-in-first-out (FIFO) algorithm for managing the resources, thereby removing those resources that are likely to be out of date or less frequently used. In other embodiments, the resource manager server 220 may remove the less frequently accessed resources first.

Examples of Data Flow Between Components

With reference now to FIGS. 3-5 the interaction between various components of the resource delivery environment 100 of FIG. 1 will be illustrated. For purposes of the example, however, the illustration has been simplified such that many of the components utilized to facilitate communications are not shown. It can be appreciated that such components can be utilized and that additional interactions would accordingly occur without departing from the spirit and scope of the present disclosure. In addition, for the purposes of simplicity, communications between user computing devices of the same LAN are shown via direct arrows even though, in some embodiments, such communication may go through the router/access point. As shown herein, data flow arrows going through the router/access point are meant to represent data flowing out a LAN and to the NSP, or out of the NSP and to the LAN.

Further, FIGS. 3-5 outline the temporal flow of data between the various components of the resource delivery environment 100. In particular, the circled numerals of FIGS. 3-5 represent an illustrative order in which data may flow between the various components according to one embodiment. In other embodiments, the functions outlined by the circled numerals may be performed in a different order, and may include fewer or additional functions.

FIG. 3A illustrates one embodiment of the flow of data for uploading and requesting a resource within the resource delivery environment 100. The flow of FIG. 3A already assumes that the user has configured user computing devices 110, 111, 112 with resource manger clients and servers. In addition, the flow assumes that each of the user computing devices 110, 111, 112 has a user's local allocation for resources and the user has established with NSP 105 a user's NSP allocation for resources.

Prior to (1), a user may select a resource stored on user computing device 110 to upload to the NSP 105. The selection of the resource may be done via a user interface component of the resource manger client 210. At (1), the resource is transmitted over the network 180 to NSP 105, where it may be stored in the user's NSP allocation of storage 107, 109. Once the NSP 105 stores the resource, it may update the metadata associated with resource and transmit the updated metadata, at (2), to the user computing devices 110, 111, 112 running a resource manager server instance. In the embodiment of FIG. 3A, the metadata for the resource might contain a unique resource ID assigned to the resource by the NSP 105 so that the resource may be identified across computing systems. The metadata may also provide location information of the resource indicating that the most recent version of the resource is available at the NSP 105 and at user computing device I-A 110. Thus, after the metadata has been updated to the user computing devices 110, 111, 112, each resource manger server instance is aware that the most recent version of the resource may be obtained from either user computing device I-A 110 or NSP 105.

At (3), a user may request the resource at user computing device II-A. Since user computing device II-A does not have a copy of the resource, the resource manager server executing on user computing device II-A may access its copy of the received metadata to determine if the resource is available within LAN A 115. After accessing the metadata, the resource manager server of user computing device II-A may determine that the resource is available from user computing device I-A 110 and request the resource from user computing device I-A 110. At (4), the user computing device I-A receives the request for the resource. In some embodiments, user computing device I-A may verify that user computing device II-A 111 has been authorized or authenticated to receive the resource. Once user computing device II-A has been authorized or authenticated, user computing device I-A provides the resource to user computing device II-A. Thus, the resource was provided to the user computing device II-A without the need to leave the LAN A, thereby resulting in more efficient provision of the resource.

FIG. 3B illustrates one embodiment of the flow of data for editing and uploading a resource. The embodiment of FIG. 3B is an extension of the flow of data from FIG. 3A; that is, the resource was uploaded at first through user computing device I-A 110 to the NSP 105 and then user computing device II-A 111 requested and received the resource from user computing device I-A 110. Moving to (1) of FIG. 3B, a user may edit the resource at user computing device II-A. After editing the resource, the version of the resource stored in the user's local allocation of user computing device II-A is the most recent version of the resource, whereas the version stored on the NSP 105 and the version stored on user computing device I-A is out of date. The user, after editing, the resource may upload the resource to the NSP 105 at (2). After uploading the resource, the NSP 105 may update the metadata associated with the resource and then, at (3), send the updated metadata to each of the user computing devices 110, 111, 112. Upon further requests for the resource from the user using user computing device I-A 110 or III-A 112, the resource manager servers may locally consult the updated metadata provided in (3) and request the resource from user computing device II-A 111.

The embodiment of FIGS. 3A and 3B illustrates that metadata may be updated at the NSP 105 and then transmitted to user computing devices 110, 111, 112. However, the transmission of metadata may vary from embodiment to embodiment. For example, in other embodiments, the metadata may be stored at the NSP 105, and user computing devices may request the metadata from the NSP at the time the user requests a resource. In other embodiments, the NSP 105 may send updated metadata to one of the user computing devices 110, 111, 112 that acts a “master” of the other user computing devices in the LAN. As such, the master user computing device may provide metadata on request to the other user computing devices connected to the LAN that are participating in the resource delivery environment 100.

FIG. 3C illustrates another embodiment of the flow of data for editing and uploading a resource. The embodiment of FIG. 3C is an extension of the flow of data from FIG. 3A; that is, the resource was uploaded at first through user computing device I-A 110 to the NSP 105 and then user computing device II-A 111 requested and received the resource from user computing device I-A 110. In addition, the embodiment of FIG. 3C is an alternative to the flow illustrated in FIG. 3B. In general, instead of the NSP 105 providing updated metadata to the user computing devices 110, 111, 112 after the resource was edited and uploaded to the NSP 105 as illustrated in FIG. 3B, the flow in FIG. 3C illustrates the user computing device II-A 111 providing updated metadata to the other user computing devices 110 and 112 after the resource was edited and uploaded to the NSP 105. More specifically, moving to (1) of FIG. 3C, a user may edit the resource at user computing device II-A. After editing the resource, the version of the resource stored in the user's local allocation of user computing device II-A is the most recent version of the resource, whereas the version stored on the NSP 105 and the version stored on user computing device I-A is out of date. The user, after editing, the resource may upload the resource to the NSP 105 at (2). After uploading the resource, the user computing device II-A 111 may update the metadata associated with the resource and then, at (3), send the updated metadata to each of the other user computing devices 110, 112 associated with LAN A 115. Upon further requests for the resource from the user using user computing device I-A 110 or III-A 112, the resource manager servers may locally consult the updated metadata provided in (3) and request the resource from user computing device II-A 111.

FIGS. 4A and 4B illustrates one embodiment of the flow of data for requesting a resource where resource manager servers poll each user computing device within the LAN before requesting the resource from the NSP 105. The embodiment of FIGS. 4A and 4B differs from the embodiment of FIGS. 3A and 3B in that the embodiment of FIGS. 4A and 4B do not depend on the use of metadata to determine the location of a resource. Although the embodiment of FIGS. 4A and 4B do not depend on metadata to determine the location of a resource, some embodiments may use the metadata to determine resource identifiers, version information, or status information of the resource.

FIG. 4B illustrates one embodiment of the flow of data for requesting a resource available on a local area network. At (1), the user computing device I-A 110 receives a first request for a resource from a user. The user may use, in some embodiments, the resource manager client 210 to request the resource. The requested resource may be among the resources that have been uploaded to the NSP before the user made the request. For example, the resource may be displayed in a list of all the resources available in the user's NSP allocation. In the embodiment of FIG. 4B, the resource manager server 220 determines that the requested resource is not available at user computing device I-A 110. As a result, it must request and receive the resource from either the other computing devices on LAN A 115 (user computing device II-A 111, user computing device III-A 112) or request the resource from the NSP 105.

In (2), the user computing device I-A 110 polls each of the computing devices on LAN A 115 for the requested resource. Illustratively, the user computing device I-A 110 may poll for specific resources or a generic request for all resources or sets of resources. The resource manager server 220 instance of user computing device I-A 110 may access the list or data structure of participating computing devices to determine those computing devices to poll. For example, in the embodiment of FIG. 4A, the resource manager server instance executing on user computing device I-A 110 may have discovered that user computing device II-A 111 and user computing device III-A 112 are devices participating in the resource deliver environment (that is, they are executing an instance of the resource manager server). In the embodiment of FIG. 4A, the user computing device I-A polls, or requests, the resource from each of the participating computing devices. In the illustrative embodiment of FIG. 4A, neither user computing device II-A nor user computing device III-A have the resource. As a result, both respond back to the user computing device I-A indicating the resource is not available.

Upon determining that the resource is not available on the LAN A 115, the user computing device I-A 110, at (3), may request the resource from the NSP 105. The resource manager server 220 executing on the user computing device I-A may request the resource using a resource identifier. Upon receiving the request, the NSP 105 may provide the resource to user computing device I-A 110 at (4).

FIG. 4B illustrates one embodiment of the flow of data for requesting the resource of FIG. 4A from a computing device located on the LAN A 115. The illustrative embodiment of FIG. 4B describes additional steps that may be performed after the steps illustrated in FIG. 4A.

At (1) of FIG. 4B, a user may make a second request for the resource, but the request may be made from user computing device II-A 111 instead of user computing device I-A. User computing device II-A may execute a resource manager server 220 instance that maintains a list or data structure of those computing devices that are participating in the resource delivery environment 100. The resource manager server of user computing device II-A may then consult the list or data structure and determine that both user computing device I-A 110 and user computing device III-A 112 are participating computing devices. In some embodiments, the resource manager server of user computing device II-A may also check to make sure that that both user computing device I-A 110 and user computing device III-A 112 have been authorized or authenticated to provide the resource. Then, at (2), user computing device II-A polls or requests the resource from each participating device: user computing device I-A 110 and user computing device III-A. As described above with respect to FIG. 4B, user computing device I-A has a copy of the requested resource and user computing device III-A does not have a copy of the requested resource. As a result, the user computing device II-A receives notification that the resource is available from user computing device I-A.

In some embodiments, the user may request the most recent version of a resource, a particular version of a resource (e.g., “version 3.2”) or may request a minimum version of a resource (e.g., “at least version 3.2”). At (3), user computing device II-A 111 may check the version of the resource available from user computer device I-A to determine if it is the requested version of the resource. In some embodiments, the most recent version of the resource may be determined by checking the metadata of the resource available from user computing device I-A against the metadata of the resource available from NSP 105. In other embodiments, the metadata of the resource available from user computing device I-A may have status information indicating that the resource is the requested version. Once the user computing device II-A verifies that the version of the resource available form user computing device I-A is the requested version, it may then request and receive the resource at (4). In some embodiments, the user computing device I-A may check the metadata of the resource to ensure that user computing device II-A has been authorized or authenticated to receive the resource before providing it. Although the illustrative embodiment verifies the version of the resource available from user computing device I-A before receiving the resource from user computing device I-A, in other embodiments, verification may occur after the resource has been received.

Turning now to FIG. 5A, an illustrative embodiment of the flow of data for pre-fetching a resource will now be described. At (1) of the embodiment of FIG. 5A, a user may upload a resource to the NSP 105. Once the resource had been provided to the NSP 105, resource availability data may be sent, at (2), to computing devices that are participating in the resource delivery environment 100. The resource availability data may be part of metadata that is periodically retrieved by resource manager server instances in the resource delivery environment 100. In the embodiment of FIG. 5A, user computing device I-A 110 (of LAN A), user computing device I-B 120 (of LAN B), and user computing device II-B 121 (of LAN B) are computing devices participating in the resource delivery environment 100. As a result, NSP 105 provides the resource availability data to each device at (2).

In the embodiment of FIG. 5A, the user computing device I-B has a pre-fetch module 230 which has been configured to pre-fetch resources. The pre-fetch module 230 may pre-fetch resources based on the type of resource (for example, word processing document, image, video) or some other criteria. At (3), the pre-fetch module 230 of user computing device I-B accesses and analyzes the resource availability data provided in (2) to determine if it should pre-fetch the resource from the NSP 105. For example, if the pre-fetch module 230 is configured to pre-fetch documents that are spreadsheets, and the resource is a spreadsheet, the pre-fetch module will request the resource from the NSP 105 at (4). If, however, the resource is an image, the pre-fetch module will not request the resource from the NSP 105 and will wait until it receives updated resource availability data. When it receives updated resource availability data, it may perform (3) again. Once the pre-fetch module 230 has requested the resource at (4), the NSP 105 may provide the resource to user computing device I-B at (5).

In the embodiment of FIG. 5A, the user did not request the resource using user computing device I-B, rather, the resource was pre-fetched from the NSP 105 automatically based on the configuration of the pre-fetch module. As stated above with respect to FIG. 2, in some embodiments, the pre-fetch module may be configured with pre-fetch parameters so that the user may customize the pre-fetch behavior of the module. By pre-fetching resources, the user computing device I-B may provide more efficient access to resources that are of interest to the user while the user is using user computing device I-B 120.

FIG. 5B illustrates one embodiment of the flow of data for requesting the pre-fetched resource of FIG. 5A from a computing device located on the LAN B 120. The illustrative embodiment of FIG. 5B describes additional steps that may be performed after the steps illustrated in FIG. 5A.

FIG. 5B illustrates one embodiment of the flow of data for requesting a pre-fetched resource available on a local area network. In the embodiment of FIG. 5B, user computing device II-B does not have a pre-fetch module configured to pre-fetch the resource. The user at (1), may request the resource using user computing device II-B 121. The resource manager server instance of user computing device II-B may then, at (2), request the resource from user computing device I-B. In some embodiments, resource manager server instance of user computing device II-B may access and analyze metadata of the resource to determine the location of the most recent version of the resource (similar to the process described in FIGS. 3A and 3B) or in other embodiments may poll all participating computing devices of the LAN B 125 to determine if the devices have the resource (similar to the process described in FIGS. 4A and 4B). After the user computing device II-B 121 requests the resource from user computing device I-B 120, the user computing device II-B 121 receives the resource at (3). In some embodiments, the user computing device II-B 121 may verify that the version of the resource available at user computing device II-A is the most recent version as described above with respect to (3) of FIG. 4B.

Examples of Process Flow

FIGS. 6A-6C illustrate examples of embodiments of the process flow for embodiments of the resource delivery environment 100. Depending on the embodiment, the processes and methods of FIGS. 6A-6C may include fewer or additional blocks and/or the blocks may be performed in a different order than is illustrated. For ease of explanation, the processes and methods will be described herein as performed by one or more specific computer systems. However, other computer systems or modules may perform the process and methods without changing the overall scope of functionality of certain embodiments. Software code configured for execution on a computing device in order to perform the methods may be provided on a tangible computer readable medium, such as a compact disc, digital video disc, flash drive, hard drive, memory device or any other tangible medium. Such software code may be stored, partially or fully, on a memory of a computing device, such as the user computing device 110, and/or other computing devices illustrated in the figures described herein to perform the respective methods.

FIG. 6A is a flowchart illustrating one embodiment of the flow of data for initiating a resource manager server instance and listening for requests for resources. At block 601, an instance of the resource manager server 220 is initiated. The resource manager service may be a daemon that is started during the start up of the user computing device 110, or in other embodiments, may be started at the user's request. In some embodiments, the initiation of the resource manager server instance may start upon the user launching the resource manager client 210. In some embodiments, at initiation, the resource manager server 220 may establish a socket server on a dedicated port to listen for any incoming socket connection requests. The resource manager server 220 may also be configured to periodically broadcast notification packets that notify any other resource manager instance on its LAN that the resource manager server 220 is available to receive requests for resources. Processing may then move to block 602.

At block 602, the resource manager server 220 detects other computing devices on the network that are participating in the resource delivery environment 100. In some embodiments, the resource manager server 220 interfaces with, or includes, a packet analyzer that detects notification packets sent by other resource manager server instances on the network. In other embodiments, the resource manger server 220 may leverage network utilities of the user computing device's 110 operating system to detect all computing devices on the LAN and then attempt to establish a connection with the detected computing devices on an established port. If the connection is successful, the resource manager server 220 will know that the computing device is executing a resource manager server instance.

Once the participating devices are detected, processing moves to block 603. The resource manager server 220 may maintain a list or data structure of available resource manager servers on its LAN. In some embodiments, the resource manager server instance may also receive resource metadata from the other resource manager server instances on the LAN. At block 603, the resource manager server 220 may also update the metadata of the resources that are part of the user's local allocation. For example, the resource manager server 220 may communicate with the NSP 105 to retrieve the metadata for all resources of the user's NSP allocation and compare it with the metadata of the user computing device 110 to determine if there have been any changes in the metadata.

After the resource manager server 220 has updated available server and resource data in block 603, at block 604, the resource manager server 220 may listen for requests for resources. In some embodiments, the resource manager server 220 may expose a port for receiving resource requests. The requests may come from other resource manager service instance daemons executing within the LAN. In some embodiments, the resource manager client 210 may request the resource manager server 220 to retrieve a resource. The resource manager client 210 may communicate with the resource manager server 220 through the listening port, or in other embodiments, may communicate with the resource manager server through an API or other software interface. In some embodiments, the resource manager server 220 may refresh the server and resource data by executing the process flow again starting with block 602. The process flow may return to block 602 after a particular time-to-live (“TTL”). The TTL may be configured by the user, or in other embodiments, may be set to a fixed value programmatically. In other embodiments, blocks 602 and 603 may be executed concurrently in a separate processing thread, thereby continuously refreshing server and resource data. At block 605, when a resource has been requested, process flows to subroutine B. Subroutine B is described in greater detail with respect to FIG. 6B.

FIG. 6B is a flowchart illustrating one embodiment of the flow of data for providing a resource in response to a request for the resource. At block 620, the metadata for the resource is accessed. In some embodiments, the metadata is local to the user computing device 110 and the resource manager server 220 may access the metadata locally. In some embodiments, the metadata may be accessed from the NSP 105, or in other embodiments may be accessed by another computing device within the LAN. The resource manager server 220 may analyze the metadata and determine that most recent version of the resource is available in the data store 204 of the user computing device at block 621. If so, processing moves to block 622 and the resource is provided to the requester. If the resource is not available in the data store 204, the resource manager server 220 may analyze the metadata to determine if the resource is available on the LAN. If the resource is available on the LAN, processing moves to block 631 where the resource is accessed from the computing device on the local network storing the resource. Once accessed, the connected data store 204 is updated to have a copy of the most recent version of the resource. Process then flows to block 622. If the resource is not available on the LAN, then the resource manager server may access the resource from the remote NSP 105. Once accessed, the connected data store 204 is updated and the resource is returned to the requester at block 622.

FIG. 6C is a flowchart illustrating one embodiment of the flow of data for initiating a resource manager server instance and listening for requests for resources. FIG. 6C is similar to FIG. 6A in that the description of the process for each block is the same for FIG. 6C as it is for FIG. 6A. The process flow for FIG. 6C, however, occurs in a different order. Specifically, in FIG. 6C, blocks 602 and 603 are performed in response to a request for a resource from a user. In the embodiment illustrated in FIG. 6C, once the resource manager server 220 has been initiated, it may listen for requests from a resource. Once it receive the request, it may then detect any participating computing devices on the LAN, update server and resource data, and move to subroutine B to retrieve the resource.

Although certain embodiments have been described in the context of a local area network, other embodiments of the resource delivery environment may be used to manage resources across networks where accessing a resource from remote NSP may less efficient than accessing the same resource from a node within the network.
